Blockchain-based visual data provenance and integrity verification system

By using a blockchain-based visual data traceability and integrity verification system, dynamic security assessment is performed using composite signatures and Bayesian models, and hash time-locked contract transactions are constructed. This achieves data security and flexible response in a quantum computing environment, ensuring long-term data reliability and real-time monitoring, and solving the problem that existing technologies cannot cope with the threat of quantum computing.

AI Technical Summary

Technical Problem

Existing digital signature mechanisms are unable to cope with the potential threats of quantum computing, security assessment methods are static and cannot respond to data changes or risks in real time, and verification mechanisms have poor flexibility.

Method used

A blockchain-based visual data traceability and integrity verification system is adopted, including a dual-signature first-store module, a remaining security assessment module, a rollback-and-resign module, and an interlocking verification module. Elliptic curve algorithm and lattice-based quantum-resistant algorithm are used to generate composite signatures, and Bayesian model is combined for security assessment. Hash time-locked contract transactions are constructed, and a dual-track verification strategy is adopted to monitor the signature status in real time and trigger responses.

Benefits of technology

It enables dynamic security assessment and real-time response of data in a quantum computing environment, ensuring long-term data security and reliability. Through a dual-track verification mechanism, it can still guarantee data security even when quantum algorithms are not widely used, and improve the system's automated processing capabilities.

Abstract

The application discloses a blockchain-based visual data traceability and integrity verification system, relates to the technical field of data traceability, and is used for solving the potential threat that the current digital signature mechanism may not be able to cope with quantum computing, especially in important data evidence, the security evaluation method is usually relatively static, and the change or risk of data cannot be responded to in real time, the digital signature system cannot flexibly cope with the security problem in a long period of time, and the verification mechanism may be single and poor in flexibility in the security verification process. Through the introduction of anti-quantum encryption technology, dynamic security evaluation, rollback and resign mechanism and intelligent response verification, the problems of vulnerability to quantum computing threat, inaccuracy of data security evaluation, long-term validity of signature and poor flexibility in the prior art are solved, and the innovations enable the system to better adapt to the changes of future technologies while ensuring the long-term reliability and security of visual data.
